Two-Pinned Arch

This product helps students to understand how loads affect the horizontal reaction forces in a two-pinned arch. This product includes additional masses so students may apply a uniformly distributed load (UDL) across the span of the arch for comparison of results with a single point load.

Learning Outcomes

  • Horizontal reactions due to a uniformly distributed load on a statically indeterminate structure
  • Influence lines and superposition
  • Lines of thrust in an arch
  • Graphical construction of a bending moment diagram for point loads
  • Maximum bending moments due to a load on an arch


  • A simplified version of a realistic structure to give students an understanding of real-life structures
  • Includes multiple loads for many combinations of loads including uniformly distributed loads (UDLs)
  • Supplied with a storage tray to keep smaller items safe
  • Direct reading of horizontal reaction for quick and simple experiments
